Abstract
The invention relates to a boiler energy saving and emission reducing device which comprises a smoke and oxygen generator, a boiler, smoke pipes and an induced draft fan. The smoke and oxygen generator is of a three-layer tank structure, a smoke and oxygen mixing bin is arranged on the upper portion of the smoke and oxygen generator, a heat recycling bin is arranged in the middle of the smoke and oxygen generator, a coal smoke bin is arranged at the bottom of the smoke and oxygen generator and is communicated with the smoke and oxygen mixing bin via the corresponding smoke pipe which penetrates the heat recycling bin, and the smoke and oxygen generator, the boiler and the induced draft fan are communicated with one another via the corresponding smoke pipes to form a recyclable channel. The boiler energy saving and emission reducing device has the advantages that a large quantity of coal smoke can be repeatedly combusted and utilized in cycles, and residual smoke dust can be discharged via a safety smoke outlet if the residual smoke dust is available; obvious practical effects can be realized, and the coal smoke emission load can be reduced by 80%; the boiler energy saving and emission reducing device is simple in structure and low in cost and is environmental friendly, all coal-fired and gas-fired boilers can be modified by the aid of the boiler energy saving and emission reducing device, energy can be saved, and a new-generation boiler energy saving and emission reducing scheme can be optimized.
Description
One, technical field:
The present invention relates to a kind of saving emission reduction device of boiler, by cigarette Oxygen Generator, boiler, smoke pipe, air-introduced machine, formed.
Two, background technology:
Environmental protection is the problem that the whole mankind faces jointly; in the energy consumption structure of China; coal accounts for 70% left and right. the boiler that the coal of take is at present comburant by chimney directly by coal smoke waste heat discharged in air; cause pm2.5 value in air to continue to increase; weather continues to warm; haze weather increases, so boiler energy-saving emission-reduction technical scheme is significant in the application of field of Environment Protection.
Three, summary of the invention:
The object of the present invention is to provide a kind of saving emission reduction device of boiler.The present invention is achieved through the following technical solutions: a kind of saving emission reduction device of boiler comprises cigarette Oxygen Generator, boiler, smoke pipe, air-introduced machine formation is characterized in that: described cigarette Oxygen Generator is a kind of three layer box body structures, top is cigarette oxygen mixing bunker, middle part is energy recovery storehouse, bottom is coal smoke storehouse, between coal smoke storehouse and cigarette oxygen mixing bunker, have a smoke pipe that passes through energy recovery storehouse to be communicated with, cigarette Oxygen Generator, boiler, air-introduced machine are communicated with and are formed path capable of circulation by smoke pipe.
Described cigarette oxygen mixing bunker top is provided with outlet flue, water inlet, safe exhaust opening.
Described energy recovery storehouse one side is provided with heating outlet, and the heating outlet of the outlet flue on cigarette oxygen mixing bunker top and energy recovery storehouse one side is connected with the air inlet of air-introduced machine after by smoke pipe parallel connection.
Described fan out draft is connected with the burner hearth of boiler.
Described energy recovery is provided with heat radiating metal fin in storehouse.
Described smoke pipe is provided with air door.
Four, accompanying drawing explanation
Accompanying drawing 1: be this patent structural representation
Five, the specific embodiment:
With reference to accompanying drawing 1, the outlet flue 2 of described boiler 1 enters mouth 5, smoke pipe 6, outlet flue 8, smoke pipe 17 by cigarette Oxygen Generator 3, and air inlet 10 air outlets 11 of air-introduced machine 9, form path capable of circulation after the burner hearth 12 of boiler 1 is connected.During boiler 1 burning, water inlet 13 by cigarette oxygen mixing bunker 7 tops adds appropriate water in cigarette oxygen mixing bunker 7, after the coal igniting in boiler 1, open air-introduced machine 9 coal smokes can enter the fin 15 that coal smoke storehouse 4 is now arranged in the energy recovery storehouse 14 on 4 tops, coal smoke storehouse by outlet flue 2 can be by the exhaust-heat absorption of coal smoke, this part heat energy forms steam by the water heating and gasifying in cigarette oxygen mixing bunker 7, coal smoke enters cigarette oxygen recovery bin 7 by smoke pipe 6, now coal smoke mixes with steam, mixed coal smoke and steam enter burner hearth 12 primary zones under the effect of air-introduced machine 9 by air outlet 8, steam can make coal layer loose, the oxygen that contains 37% hydrogen 16% in steam, it is the indispensable condition of burning that hydrogen possesses flammable oxygen, after steam and carbon meet, can produce water gas reaction and generate carbon monoxide and hydrogen, it is looped around the reaction zone that carbon outer layer forms thin layer, wherein combustion of hydrogen can produce microexplosion, thereby the inorganic salts duricrust producing while making coal burning is popped, improve the after-flame degree of fuel gas, boiler slag carbon content reduces, the fast furnace temperature of flame propagation is high, the gases such as sulfur dioxide its concentration after second-time burning in coal smoke reduces greatly simultaneously, partial heat energy in energy recovery storehouse 14 enters smoke pipe 17 by heating outlet 16 and again enters the interior participation burning of the burner hearth 12 saving energy under the effect of air-introduced machine 9.Smoke pipe 17 is provided with adjustable air-introduced machine 9 air quantity of air door 19, when boiler 1 needs conflagration, corresponding unlatching air door 19 increases intake, when boiler 1 need to burn at a slow speed, the corresponding air door 19 of closing reduces intake, a large amount of coal smokes can be utilized by repeated combustion in circulation, if any residue flue dust, can discharge by safe exhaust opening 18.This patent practical function is remarkable, and soot emissions amount can reduce by 80%.This patent is simple in structure, and all fire coals, gas fired-boiler all can be transformed, with low cost, not only energy-conservation but also environmental protection, be boiler energy-saving emission-reduction scheme of new generation preferably.
